The Option for Online Services when CAPTCHA is No Longer Secure

Computers are more and more powerful, with AI is better and better and even with quantum computing the CAPTCHA may no longer be useful.

Software can bypass the CAPTCHA in near future. These are the better option and always safe for online services to make their APIs safe from bruteforce attack:

• Throttle the requests: Some APIs can be only called after a small or large period of time
• Counter limit: Similar to TPM (PC), TEE (mobile), APIs can apply some request rating such as max number of requests in a period of time.

Although CAPTCHA is no longer safe in future, but it's still good for now in 2025.
